Stock timing is 8* btdc This sucks to say it plainly. Ive run around w/ 25* timing advance, i wouldnt run it for a long trip but around town wont hurt it and i had Gobbs of Power. But just to play it safe i leave it at 15* btdc and my yota has much more power than w/ stock timing. So i say advance ur timing about 7* and check back
